更新CMS上的新聞

Question

所以我一直在試圖爲客戶編寫一個CMS來更新他們的網站。我正在試圖讓更新新聞腳本起作用，並且我想知道如何讓腳本不僅更新新聞本身，而且還更新標題。下面是該腳本：

PHP：

//used to get data from previous page. $previous_title was so I can use it to set the where in the update query. 
    if($_GET['title']) { 
      $title = $_GET['title']; 
      $previous_title = $_GET['title']; 
    } 
    if($_POST['title']) { 
      $title = $_POST['title']; 
      $news = $_POST['news']; 

      //used to update both news and title 
      mysql_query("UPDATE `News` SET `Title`='$title', `Content`='$news' WHERE `Title`='$previous_title'"); 
    header("Location: viewNews.php"); 
    } 

HTML：

   <form id = "addNews" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>"> 
       <input type="hidden" name="hidden" id="hidden" value="hidden" /> 
       <input type="text" name="title" size="68" id = "title" value="<?php echo $query['Title'];?>"/><br/><br/> 
       <textarea name="news" id="news"><?php echo $query['Content'];?></textarea><br /> 
       <input type="submit" value="Update News"/> 
       </form> 

謝謝！

Answer 1

更新詢問要更新這兩個領域Title & Content

UPDATE `News` SET `Title`='$title', `Content`='$news' WHERE `Title`='$previous_title 

，但如果要更新，然後唯一的新聞您的SQL是這樣的：

UPDATE `News` SET `Content`='$news' WHERE `Title`='$previous_title 

你應該好好$previous_title 因爲護理在這種情況下$previous_title可能不可用

if($_POST['title']) { 
      $title = $_POST['title']; 
      $news = $_POST['news']; 

      mysql_query("UPDATE `News` SET `Title`='$title', `Content`='$news' WHERE `Title`='$previous_title'"); 
    header("Location: viewNews.php"); 
    }
